“Obstetrics and Gynecology, Union Hospital, Tongji Medical college, Huazhong University of Science and Technology, Wuhan, China The aim of this study was to investigate the impact of uterine contraction on the immune environment within the uterus during parturition. Uterine smooth muscle cells (USMC) were isolated from uterine myometrial tissues and cultured. The effects of cyclic stretch MK-1775 datasheet on mRNA and/or protein expression
of IL-8, Groα, and pro-MMP-1 by USMC were measured using RT-PCR and ELISA. Neutrophil chemotactic activity in conditioned media was evaluated using migration assays. To evaluate the effect of progesterone (P4), USMC were pretreated with P4 for 24 hr. Cyclic stretch increased IL-8 and Groα mRNA and protein and pro-MMP-1 production
significantly. Supernatants from stretched cells induced neutrophil chemotactic activity significantly; these effects were abrogated by anti-IL-8 or Groα neutralizing antibodies. Stretch effects were reduced by P4. These results suggest that uterine contraction may induce neutrophil infiltration and MMP-1 production, which may contribute to cervical ripening and rupture of membrane. The inhibitory effects of P4 may explain the mechanism by which progestin prevents preterm labor. “
“Rejection of solid organ allograft involves alloreactive T-cell this website expansion. The importance of NF-κB and NFAT in this process is underscored by the therapeutic efficacy of immunosuppressive agents, which target the two transcription factors. Since calpains, calcium-activated proteases, are involved in the activation of NF-κB and NFAT, we investigated the role of calpains in allograft rejection. In human transplant kidneys undergoing acute or chronic rejection, we show an increased expression of CAPN 1 gene Liothyronine Sodium encoding μ-calpain, associated with a marked expression of μ-calpain, mainly in infiltrating T cells. To address the role of calpain in rejection, we used a skin transplant model in transgenic mice
expressing high levels of calpastatin, a calpain-specific inhibitor. We show that calpain inhibition extended skin allograft survival, from 11 to 20 days. This delay was associated with a limitation in allograft infiltration by T cells. In vitro, calpain inhibition by calpastatin transgene expression limited dramatically T-cell migration but, unexpectedly, increased slightly T-cell proliferation. Amplification of IL-2 signaling via the stabilization of IL-2R common γ-chain provided an explanation for the proliferation response. This is the first study establishing that calpain inhibition delays allograft rejection by slowing down T-cell migration rather than proliferation. Solid organ transplantation represents an important means of treating end stage organ failure.
